Array, which sometimes called Lists, organizes items sequentially in memory,

i.e. one block of memory after another.

Needless to say that array is one of the most common and useful data structure you can use as a developer, either you are coding in JavaScript, Java, or any other programming language.

Note, that array is much more efficient when it comes to storing data and iterate over that data, one by one, especially if the indices are known.

In JavaScript, an array is a data structure that contains a list of elements that store multiple values inside a single variable.

The big advantage of JavaScript arrays lies in the array methods.

There are a bunch of built-in methods that are very helpful and useful when it comes to JavaScript arrays.

We can apply those built-in methods on our arrays — while each method has a unique functionality that performs some manipulation or calculation on them.

Those built-in methods can save us time and redundant lines of code for writing them from scratch.

Therefore, today we will cover 8 array methods, which will make you a better JavaScript developer.

For this tutorial, we are going to use the following array examples :

const numbers = [4, 38, 10, 9, 57, 213];
const names = ["Josh", "Alex", "Ron", "David", "James", "Jimmy"];
const store = [
  {name: "Laptop", price: 250},
  {name: "TV", price: 120},
  {name: "Printer", price: 80},
  {name: "Xbox", price: 100},
  {name: "Headphones", price: 50}
]
